[0001] The utility model relates to the technical field of injection molding, in particular to a high-efficiency injection molding structure of an injection molding machine. Background Art
[0002] Injection molding machines are the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machines are generally equipped with a feed hopper. When in use, the material is poured into the feed hopper, and then the material enters the injection molding machine under the action of gravity.
[0003] For example, the rapid injection molding mechanism of an injection molding machine with the authorization announcement number CN218488951U is provided with a pressure plate, a scraper, a driving cylinder, a driving motor, a stirring shaft and other structures. The pressure plate pushes the material out of the discharge port of the lower hopper through air. During the pushing process, the scraper scrapes the material on the side wall of the lower hopper, which can speed up the discharge and improve the injection molding efficiency. However, the mechanism needs to repeatedly operate the driving cylinder and the driving motor during use, which is troublesome to operate, and the inner wall of the hopper needs to be cleaned twice, which is not convenient to use. Therefore, an efficient injection molding structure of an injection molding machine is proposed for improvement. Utility Model Content
